Apiilicatioxi'fil'ed fiovenlber 1 2, 1918. 7 Serial No. 262,126.

To all whom it may concern."

Be it knowmthat LARTHUR Bos'rwrcx, a citizen of the United States, and a resident of St. Albans, in the county of Franklin and State of Vermont, have invented new and useful Improvements in Chairs, of which the following is a specification.

This invention relates to chairs and has particular reference to chairs of the folding type designed particularly for the aid and comfort of hospital patients, although not restricted to such use.

An important object of the invention is to provide a chair of the above mentioned character which may be easily folded into a compact form, thereby making possible easy transportation of the same.

A further object of the invention is to provide in a chair of the above mentioned character a means whereby the lower limbs of the patient may be supported in a restful position when the body of the patient assumes a reclined position and in which a change of position is possible without adjustment or external aid.

A further object of the invention is to provide a chair which is strong, durable and inexpensive to manufacture.

Other objects and advantages of the invention will be apparent during the course of the following description taken in connection with the accompanying drawings.

In the drawings, forming a part of this specification and in which like numerals are employed to designate like parts throughou the same,

Figure 1 is a perspective view of a chair embodying my invention, the same being shown in an extended or seating position,

Fig. 2 is a side elevation of the chair, the same being shown in a partially folded position, and,

Fig. 3 is an enlarged detail view of a portion of a leg showing a chain connected thereto.

In the drawings, wherein for the purpose of illustration is shown a preferred form of my invention, the numeral 5 indicates a pair of supports to each of which is connected intermediate the ends thereof pairs of legs 6, the legs 6 being reinforced by means of braces 7 and provided with chains 8 in order t limit the movement thereof when moved from a closed position to an open position as clearly shown m Fig. l. The supports 5 are provided relatively near the lower ends thereof withoffsets 9 to which are pivotally connected arms '10 which are in turn pivotally connected to a frame having side members 11. To the side members 11 there is pivotally connected a second pair of arms 12, which arms in turn are pivotally connected to the lower ends of the supports 5 as clearly shown. To the supports 5, appreciably near the center thereof, is connected a pair of beams 13, the beams being connected at one end thereof by a rod 14; to which is connected a pair of chains 15, the chains being in turn connected to the legs 6, as shown at 16. To substantially a half of the supports 5 and the beams 13 there is suitably secured a canvas 17, which canvas is preferably sagged as clearly shown in Fig. 1. This canvas is supported at the ends of the beams 13 by means of a cord 18 and is secured at its longitudinal edges to substantially a half of the side members 11 as clearly shown.

It will be noted that the arms 10 are provided with extensions as shown at 19, which extensions serve as a means for locking the supports 5 in the position shown in Fig. 2 when it is desired to convert the chair from that of a reclining one to that of an upright one. When it is desired to use the chair for sitting rather than reclining, the supports 5 aremoved to the position shown in Fig. 2, whereupon the arms 10 and 12 are moved to the position shown therein. -When the arms- 10 and 12 are moved to the position shown in Fig. 2 the extensions as shown at 19 engage the braces 7 and serve as a'means for retaining not only the supports 5 in the position shown in ig. 2 but also the arms 10 and 12 in which position one is permitted to comfortably sit in a relatively upright position. Should it be desired to change the angle between the legs 6, this may be done by lengthening or shortening the chain 8, n adjustment of which legs is indicated by the dotted line in Fig. 2.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, andthat various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, what I claim as neW and desire to secure and protect by Letters Patent of the United States, is:

1. A chair comprising a pair of supports, a pair of legs pivotally connected to said supports, a pair of beams pivotally connected to said supports, means for limiting the movement of said beams With respect to said legs, a pair of arms pivotally connected to each of said supports, and a frame pivotally connected to said arms.

2. A Chair comprising a pair of supports, a pair of legs pivotally connected to said supports, a pair of beams pivotally connected to said supports, means for limiting the movement of said beams With respect to said legs, a pair of arms pivotally connected to each of said supports, a frame pivotally connected to said arms, and a flexible mate rial secured to said supports, beams and frame.
